2 Claims.

'Ihi'sinvention relates to an improved bathtub.

After extended use ofthe customary built-in bathtub, it frequently occurs that the top edge of the tub separates from the wall structure causing a leak between the topedge and the wall, enabling water to seep into the wall and produce damagefthereto;

It has been proposed to use attachingbrack'ets and attachments for" connecting the top edge of the tub and the wall, to avoid such separation andleakage;.but these are objectionable, since they cause addedexpense in the manufacture and extra work and trouble in the installation, and do not fully solve the difficulty.

It is the main object and purpose of this invention to provide a bathtub of the built-in type v which comprises in one unitary tub structure all of the essential means necessary for providing a constantly secure and positively leak-proof connection between the upper part of the bathtub and the wall, and thus obviate the necessity of using any separate and additional attaching members. I

Another object of this invention is to provide a built-in bathtub having integral flange means at its upper end which is arranged and equipped for conveniently and securely fastening the tub to'the wall structure to remain firmly in position; and is also arranged and equipped so as to provide a positively leak-proof bonding connection between the upper part of the tub andthe wall.

- A further object is to provide such a bathtub with an integral mounting flange which is provided with openings therein for substantially the entire length of the flange, so that fastening elements may be conveniently placed therethru into the upright frame members of the wall, no matter where these members may be located along the flange, and these openings will also serve as anchorage spaces for the finishing material of the wall.

These and various other objects and advantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing in which this invention is illustrated in its preferred form of construction; it being understood that various other arrangements and forms of construction may be resorted to for carrying out the objects and purposes of this invention.

In the drawing:

Fig. 1 is a perspective view of a bathtub embodying this invention in its preferred form of construction.

2 and 3 are enlarged detail sectional views thereof, taken respectively on lines 2-2 and 3-3 of Fig. 1.

Fig. 4 is a partial sectionalview of the tub installed and secured to the vertical frame mem of Fig. 4, but taken intermediate the frame members.

In the drawing my improved bathtub is illustrated in its preferred form of construction, comprising the customary main portion or body ill from the upper edge of which extend the ledges or shelf portions substantially horizontally outwards, including the front and rear side ledges II and I2, and the two end ledges l3 and I3. From the front ledge ll depends the front wall or apron l4, integral therewith and depending down therefrom to the floor.

The rear ledge I2, and also one or both of the end ledges I3 and I3, according to whether one or both of the ends are built into the wall structure, are provided with upwardly extending flanges I6, and l! and I1, respectively. These upstanding flanges are integral with their respective horizontal ledges l2, and I3 and I3. Slots l8, and I 9 and I9, are provided respectively in said flanges l6, and I! and I1, and extend horizontally lengthwise thereof. Solidportions or vertical ribs 20 are retained at the corner parts of these flanges, and similar solid portions or ribs 20' are left unslotted between the slots in said flanges, apertures 2| being provided in said solid portion or ribs, as best shown in Fig. 1.

The slots l8, l9 and I9, provide openings along substantially the entire length of the flanges l6,

l1 and I1, and more fully so when the apertures 2| are considered in conjunction therewith, wherethru securing elements 22 can be conveniently entered at any desired position along the flanges, so that such securing elements can be readily fastened into the studdings or vertical frame members 23 of the wall structure, as such members are usually spaced from 16 inches to 24 inches apart, and these elements can be conveniently driven into said members no matter where they may be located along the flanges. The securing elements used in the slots are preferably in the form of screws having laterally extending heads 22, as indicated in Fig. 4, so that the heads may be turned horizontally and passed thru the slots if desired. Screws may likewise be extended 1y on the lower part of each flange, on the tubside away from the frame member, and preferably also to provide serrations 26 along said tubside of each flange, as best shown in Fig. 3. The slots l8, l9 and I9, and the apertures 2!, provide openings thru which the finishing material of the wall, for example plaster 21, is extended, as shown in Figs. 4 and 5. This forms a'flrm bond therewith and provides a secure and positively leakproof connection between the top part of the tub and the material of the wall.

The use of this integral flange means on the tub, with the openings provided thruout the length thereof, and the securing elements fastened therethru directly into the studdings or frame members 23, make a very secure anchorage and support of the tubonto the wall structure which will endure for an extended length of time, and will also prevent any possibility of leakage at this connection.

The tub is constructed of cast iron, sheet steel,

and the like; and it is provided with porcelain or enamel on its interior and on the apron and the ledges, in anapproved manner, the flanges however being left uncoated.

I claim:

1. A bathtub consisting of a unitary structure comprising a body portion including ledge means extending horizontally outwardly from its upper end and having flange means extending substantially vertically upwardly from the outer edge thereof, said flange means being provided with slots extending longitudinally and substantially thruout the length thereof and having solid portions therebetween provided with apertures, said slots and apertures providing openings for receiving securing elements to secure the tub to upright wall members that may be located anywhere along the length of the flange means, said flange means also having groove means provided therein, which with the slots and apertures are adapted to receive the finishing material of the wall to bond the top of the tub securely and leakproof to the wall.

2. A bathtub consisting of a unitary structure comprising a body portion including ledge means extending substantially horizontally outwardly from its. upper end and having flange means extending substantially vertically upwardly from ,the outer edge thereof, said flange means being provided with slots extending longitudinally for substantially the entire length thereof and having solid portions therebetween provided with aper- -tures, said slots and apertures providing openings for receiving securing elements to conveniently secure the tub to upright frame members that may be located anywhere along the length of the flange means, said flange means also having groove means and serrations provided on the tubside, which together with the slot means and apertures receive the finishing material of the wall, thereby bonding the tub fully leak-proof to the wall.
